Clinical diagnosis of fungal infections can be perplexing due to difficulty identifying symptoms and inconclusive results from tests like CT scans and X-rays. The gold standard for laboratory diagnosis is microscopy and culture, though culture can take days to weeks and samples from deep infections are often negative. Molecular diagnosis using PCR is more sensitive and specific than other methods but specialized techniques are still needed for rapid diagnosis. Clinical diagnosis considers characteristics lesions but they can resemble other diseases, while systemic infections show no specific fungal symptoms. Modern imaging and examinations have improved accuracy but diagnosis of invasive fungal diseases remains challenging.
